What causes addiction

Parents often struggle with question: Why does addiction happen in my kid, but not somebody else's kid who use the same amount? Why does one kid become addicted and another doesn't?
It is true that part of your risk for addiction is biological, much as it is with cholesterol or cancer. Part of it is environmental, that is, if you don't have drugs or alcohol around, you are not going to become addicted to them. The more you're exposed, the greater your risk. The third component is development. When you use, if you first try something over the age of 18, only 3 percent go on to become addicted. Of those who try marijuana under the age of 15, 25 percent of those kids go on to become addicted. The risk is very, very uneven. That's why you have to understand that it's partly biological and exposure and environment, and partly development.
The fourth thing that tends to determine, is some kind of trauma. That trauma could be sexual, physical, emotional, it could also be trauma from the loss of a loved one, a child, a parent, a sibling. Those kinds of things, which are not only for the child, but for the parent. A parent may pull back after the loss of a child, and not give their child enough nurturing. That kind of rippling effect tends to turn teens to addiction.
